Answer:
Total cost of the trip was $23.575
Explanation:
As it given in the equation that
Flat rate of the taxi = $ 4
Per mile of taxi fee = $ 2.25 per mile
Now total trip taken by the person is = 8.7 miles
Now Total trip cost would be = Flat rate + Charges of miles covered
Now Let us find the price of miles covered first
Charges of miles covered = Total miles * charges per mile
Putting in the values
Charges = 2.25 * 8.7
= $19.575
Now Total trip cost = 4 + 19.575
= $23.575
